Hypothetical: Can 2.4T pistons be cut deep enough for S cams?
2.4T pistons probably do not have the pockets necessary for S cams, so can they be cut deep enough that the S cam will safely clear, while leaving enough material on the piston?
I found some 2.2S or 2.2E pistons and cylinders they would be a perfect swap, correct? Is there anything else involved to put 2.2S/E P/C set on a 2.4T motor, for example base gaskets, etc.? I thought I heard something once that the cylinder on a 2.2 is shorter due to the shorter crank stroke--true? Thanks!

I don't think there's enough material in the dome of a T piston to pocket them deep enough. Even if there was, you'd be running way too low of compression for S cams. The motor would be a dog.
I had 2.2T pistons pocketed as deep as they would go, and they just cleared Solex cams ground on E-cores with E lobe centers. You could pocket E pistons to clear S cams, but I would only do that to 2.2E pistons, or you'll still be too low on the compression for S cams. You won't have any issues with 2.2 pistons in your 2.4 motor, but make sure you have clearance between the piston skirt and case when the piston is at the bottom of it's stroke. I've never had a problem here, but others have.
